My story

I learned the whole stack because nobody else was going to.

I started in IT support, fixing other people's software. Three years later I design, build, deploy and maintain the systems a multi-purpose cooperative runs its members, elections and payroll on — alone, on our own servers. This page explains how that happened and what I want next.

What you're here for

Three people read this page. Here's the answer to each.

Hiring managers

Can he do the job without hand-holding?

Every system below went from an empty repo to real users with me as the only engineer. I set the scope, made the calls, and lived with the consequences.

Engineering leads

Will he work well on my team?

Working alone taught me to document decisions and write code my future self could pick up cold. I want reviewers now — people who will tell me when I'm wrong.

Founders and clients

Can he take this from idea to live?

Database design, API, frontend, Docker deploy, and the handover docs. You get one person accountable for the whole thing, not a handoff chain.

The arc

Support ticket to production platform, in four chapters.

  1. 2023

    IT support, and a legacy system nobody understood

    Learned the business before I ever wrote code for it.

  2. 2024

    Promoted to full-stack developer, handed the rewrite

    Shipped my first production system solo, with no one to ask.

  3. 2025

    Undid my own over-engineering, then added AI

    Judgment caught up with ambition.

  4. Now · 2026

    One platform, and room for a bigger problem

    Ready to bring the same ownership to a team.

    This year I built a centralized platform for the cooperative that brings Time Deposits, the MIS, Collections, and reporting under one roof. Its dashboards run on the accounting system's Excel exports, which I parse into the numbers management actually decides on.

    I've proven I can take a product from zero to production alone. What I want now is the part solo work can't give me: engineers who challenge my decisions, a codebase more than one person depends on, and problems bigger than I can hold in my head.

    • Unified Time Deposits, MIS, Collections, and dashboards in one platform
    • Turned accounting Excel exports into the analytics management runs on
What drives me

The four beliefs behind every decision above.

Full ownership

A bug is never someone else's layer. I learned the whole stack so nothing in a system I ship is a black box to me.

The user is a real person

I started by fixing software for the people stuck using it. I still ask whether the person on the other end will understand what I built.

Shipping over polishing

No system is ever finished — it ships, then adapts. I'd rather get it in front of users and learn than perfect it in private.

Willing to be wrong

I adopted microservices, then tore them out when the cost showed up. Reversing my own decision is part of the job, not a failure.

How I work

What that looks like on a Tuesday.

Measure before rewriting

The MIS didn't need a rewrite, it needed indexes. I look for the real bottleneck before proposing the expensive fix.

Production is the finish line

Typed TypeScript, Docker, Nginx, CI/CD, and on-prem deploys I maintain myself. Code that isn't running isn't done.

Write it down

Working alone forces documentation. Decisions, schemas, and handover notes exist so the next person isn't me from memory.

AI as a tool, not an authority

I direct Claude and Cursor, review every diff, and reject what drifts. Speed without giving up understanding.

What I'm looking for

A team that will argue with me.

I'm based in the Philippines, work remotely, and am open to full-time roles and select contracts globally. Solo work taught me to own outcomes; it also taught me what I miss without review. I want product work with real users, engineers who push back on my design, and a codebase where my decisions have to survive someone else's reading.

  • Full-stack product work — TypeScript, NestJS, Next.js, Postgres
  • Teams that review code and expect me to defend a decision
  • Systems with real users and real consequences when they break
  • Remote-first, full-time or a high-impact contract

Tell me what you're building.

If you need someone who can own a product end-to-end — or a full-stack teammate who already knows what it costs to get one live — I'd like to talk.
